"The BBC programme Rwanda, The Untold Story, includes interviews with US-based researchers who say most of those killed may have been Hutus, killed by members of the then-rebel Rwandan Patriotic Front (RPF), which has been in power since 1994.

The programme also included interviews with former aides of RPF leader President Paul Kagame, accusing him of plotting to shoot down the presidential plane - the act seen as triggering the slaughter."
